DYEING-MAGI-IINE.

Application filed July 21, 1909. Serial No. 508,704.

To all whom it may concern:

Be it known that I, JULrUs LEISEL, a citizen of the United States, and a resident of Charlotte, in the county of Mecklenburg and State of North Carolina, have invented a new and Improved Dyeing-Machine, of which the following is a full, clear, and exact description.

The invention relates to machines for dyeing cotton and wool in the raw or in the manufactured state, and such, for instance, as shown and described in the Letters Patent of the United States, No. 7 82,147 granted to me on February 7, 1905.

The object of the present invention is to provide a new and improved dyeing machine, arranged for dyeing either loose material, or yarns wound on a beam, and provided with a circulating system for circulating dye liquor or clear water through the vat and the material contained therein, and provision is made by an overhead mechanism for manipulating the perforated vat cover and the false bottom, between which the material is laid, the said circulating system having a pump adapted to be driven.

by a reversible motor, which is also. used for actuating the said overhead mechanism in either direction.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indi cate corresponding parts in all the views.

Figure l is a side elevation of the dyeing machine, part of the foundation being shown in section; Fig. 2 is an elevation of the right-hand end of the machine, the motor and driving gear for the overhead mechanism being omitted; Fig. 3 is a sectional side elevation of the machine, arranged for dyeing loose material; Fig. 4: is a like view of the same and showing the perforate cover and perforate false bottom in raised positions; Fig. 5 is a sectional plan view of the same, on the line 55 of Fig. 1; Fig. 6 is a sectional side elevation of the double valve and by-pass for connecting the outflow pipe of the circulating pump with the storage tank pipe; Fig. 7 is a cross section of the same on the line 77 of Fig. 6; Fig. 8

is a sectional side elevation of the double valve for connecting the well pipe with the return pipe of the circulating pump; Fig. 9 is a sectional side elevation of the latch for locking the perforate cover in raised position; and Fig. 10 is a sectional side elevation of the dyeing machine, arranged for dyeing yarns wound on a slasher beam.

A vat A, of rectangular or other suitable shape, supports at its bottom A a false perforated bottom B, having lugs B adapted to rest on the vat bottom A, to support the false perforated bottom B a distance above the vat bottom A, with a view to form a circulating space or a chamber A for the water, dye liquor or other liquid, as hereinafter more fully described. When dyeing loose material, it rests onthe false bottom B, and is engaged on top by a perforate cover C, to confine the loose material between the false bottom B and the said cover G a distance below the level of the liquor in the vat. The cover C is provided at its ends and sides with an upwardly extending annular flange C, and on the bottom of the cover along its margin is arranged a tongue C adapted to engage a corresponding groove A formed in an outwardly-extending annular offset A on the upper portion of the vat A, as plainly indicated in Figs. 8 and 4. A packing C of suitable material is interposed between the flange C and the offset A to provide a tight joint between the flange C and the oflset A, so that the circulating liquid is not liable to leak past the joint, and consequently passes through the perforations in the cover C.

In the circulating space A extend a se ries of nozzles D, passing through the bot tom A and connecting with an outflow pipe D, leading from a circulating pump E of any approved construction. The return Specification of Letters Patent, P t ted N 28, 1911.

pipe D for the circulating pump E connects with an overflow chamber F arranged on the right-hand end of the vat A, and having its upper 'or inlet end opening into the vat at a distance above the oflset A and the cover G, when the latter is in position in the vat, as indicated in Fig. 3. The entrance end of the overflow chamber F is covered by a grated or slatted cover F, preferably inclined, so as to insure a ready flow of the dye liquor or other liquid from the upper end of the vat A into the overflow chamber F. Now when the loose material to be dyed is in position in the vat between the bottom B and the cover C, and the vat is filled with dye liquor and the pump E is started, then the dye liquor is forced through the pipe D and the nozzles D into the circulating space A from which the liquor rises through the perforated false bottom B and through the material, to finally pass through the openings in the cover C and through the slots in the cover F into the overflow chamber F and by way' of the pipe D back to the circulating pump E. By making the cover F in the form of spaced slats, any loose matter or material carried along with the dye liquor and striking the inclined slats, is pushed up the same and out of the direct flow of the dye liquor. Theoperator with a rake can readily remove the gathered extraneous matter.

The nozzles D are preferably four innumber and are grouped around a well G, the same as described in the Letters Patent of the United States above referred to, so that further description of the same is not deemed necessary, it being understood that the liquid in the circulating space A is caused to travel in a circular path around the well G, for the foreign insoluble or other extraneous matter in the liquid to gravitate toward the well G, to finally drop into the same. The lower portion of the well G leads to a pipe G connected by a double Valve H with the return pipe D and which double valve H serves to close the pipe G or to connect the same with the pipe D at the time the double valve closes the return pipe D to the overflow chamber F, and connects the pipe G with the pipe D and the circulating pump E. When this connection is made, the outflow pipe D is closed to the nozzles D and the circulating space A by a double valve I, which serves to connect the circulating pump E with a pipe I leading to a storage tank.

The return pipe D is connected by a pipe J, having a valve J, with a water supply, and a valve D is arranged in the return pipe D between the valve H and the pipe J, to close the pipe D by the valve D to the valve H. Now when the valve J is opened and the valve I connects the pump E with the pipe D, and the pump is started, then water is pumped by way of the pipe J, pump E, pipe D and nozzles D into the circulating space A to pass through the perforated false bottom B, the material, and the covers C and F into the overflow chamber F, from which leads the pipe D nowclcsed to the valve D From the overflow chamber F leads a drain pipe K, having a valve K which is now opened, so that the wash water circulating through the material and passing into the overflow chamber F can flow by way of the pipe K to a suitable place of discharge.

By the arrangement described, the dye liquor can be readily circulated through the vat and the material contained therein for any desired length of time, to insure a through dyeing of the material, and when the dyeing is completed, the attendant in charge changes the positions of the valves 'to allow the pump to pump the liquor by way of the pipe I to a storage tank, for further use. If the liquor is, however, spent and of little or no Value, it can be run to waste. After the liquor is removed, the at tendant again changes the valves, to connect .the water supply pipe J with the cir- -culating pump E, for the latter to force clear water through the vat and the material contained therein, the water after passing through the material and into the overflow chamber F being allowed to drain off by way of the now open drain pipe K.

In order to heat the dye liquor, use is preferably made of a steam heating pipe L, arranged in the overflow chamber F and connected with a suitable steam supply. By this arrangement undue pressure from eX- pansion of the heated liquor or the formation of gases is prevented, as the overflow chamber F is open at the top to the atmosphere. In order to avoid undue pressure from gases in the vat A, an escape port a is formed in the partition F separating the vat from the overflow chamber F, the port connecting the vat with the overflow chamber immediately below the offset chamber Ad (see Fig.

WVhen dyeing yarns wound on a slasher beam M, the latter rests on the false bottom B, and use is made of a non-perforate cover C adapted to be seated on the offset A*, the same as the cover C (see Fig. 10), as previously explained. The beam M is provided with a hollow perforated hub M, end flanges F and a shaft M extending centrally in the hub M, the left end of which is closed and the right open end is seated against a packing F 3 in a seat F formed in the partition F 2 and opening into the overflow chamber F. The hub M is drawn into firm contact. with the packing F by a wedge M abutting against the seat F Now when the pump E is running, the dye liquor is forced into the vat, through the yarn, and by way of the perforated hub M of the beam M is passed into the overflow chamber F, from which the dye liquor returns to the pump E, to be again sent through the vat and the yarn until the latter is thoroughly dyed. The solid, cover C is secured to the perforate cover C by screws C or other fastening means, and the cover C is held locked in place, raised or lowered, either when used in dyeing loose material or when carrying the solld cover C by means hereinafter described in detail.

l/Vhen dyeing loose material the solid cover C is dispensed with and the seat F is closed by a plug l 5 drawn against the packing F by the wedge h/ 4 engaging the stem M of the plug 1 as will be readily understood by reference to F ig.3. The lefthand end of the shaft M terminates at the closed end of the hub M and is preferably made hollow for the insertion of a journal when using the beam M in a warping machine or a slasher. It is understood that the journal is removed to provide room in the vat A for the beam when shifting the latter axially, as hereafter explained.

The cover C is hung on links N, pivotally connected with bell crank levers N, fulcrumed on a frame O, mounted to swing at O on the right-hand end of the vat A. The free end of the frame O is adapted to be locked in place by links O and removable pins O of which the links O are pivoted on lugs A, cast on the left-hand end of the vat A. The bell crank levers N above mentioned are pivotally connected with each other by a link N having an angular arm N pivotally connected with a nut N screwing on a screw rod N mounted to turn in a bearing N trunnioned on a bracket N attached to the frame O. A crank arm N is secured on the screw rod N and is under the control of the operator for turning the screw rod N with a view to move the nut N lengthwise of the screw rod, to impart a swinging motion to the bell crank levers N by the link N the swinging motion of the bell crank levers N causing up or down movement of the links N and a corresponding movement of the cover C, to move the latter to or from its seat on the offset A. By the arrangement described, the cover O can be pressed down with suflicient force to insure a proper seating of the cover on the offset A, and to hold the material in position between the cover and the perforated falsebottom B. It is also understood that when the solid cover C is attached to the perforated cover C and the latter is pressed down, then the solid cover C is firmly seated on the offset A the joint being rendered tight by the packing C After the cover C is unseated and it is desired to move the cover C out of the vat A and with it the cover C in case the latter is used, then the frame O is unlocked by withdrawing the pins O and swinging the frame 0 upward into the position shown in Fig. 4, thus raising the cover O clear of the vat. For the purpose mentioned the swing frame O is connected near its free end with ropes or cables P, winding on drums P secured on a shaft P journaled in suitable bearings arranged on an overhead framework A, supported from the vat A, as plainly indicated in the drawings. On one end of the shaft P is secured a worm wheel P in mesh with a worm P mounted to rotate loosely on a shaft Q, extending longitudinally and journaled in suitable bearings on the overhead frame-work A. The worm P is provided with a clutch member P adapted to be engaged by a clutch member P, mounted to slide on and to turn with the shaft Q, and engaged by a shifting lever P fulcrumed on theoverhead frame-work A and under the control of the attendant of the machine. l/Nhen the shaft Q is rotated and the shifting lever P is swung outward from its normal position of rest shown in Fig. 1, in the direct-ion of the arrow a then the clutch member P is moved into engagement with the clutch member P to rotate the worm P and consequently the worm P the shaft P and the drums P, to wind up or unwind the ropes or cables P according to the direction in which the shaft Q is rotated. Thus when the drums P are rotated to wind up the ropes or cables P, then frame 0 and with it the perforate cover O are swung upward into the raised position illustrated in Fig. 4, and when the drums P are rotated in the reverse direction then the ropes or cables P unwind, to allow the frame 0 and with it the cover C to swing downward into the position shown in Fig. 3, the cover G being independently moved into final position by the operator' turning the screw rod N as previously explained.

The shaft Q, is provided at one end with a sprocket wheel Q, connected by a sprocket chain Q with a sprocket wheel Q mounted to turn loosely on the motor shaft R of a reversible motor R of any approved construction. The sprocket wheel Q is provided with a clutch member Q adapted to be engaged by the clutch member S of a double clutch, mounted to slide on and to turn with the motor shaft R, and controlled by a shifting lever S under the control of the attendant. The double clutch referred to is also provided with a clutch S adapted to engage a clutch member E- secured on the shaft E of the circulating pump E, so that when the clutch member S engages the clutch member E, then the circulating pump E is driven, and when the double clutch is shifted to the right and the clutch member S engages the clutch member Q, then the sprocket wheel Q is driven, and its rotary motion is transmitted by the chain Q and the sprocket wheel Q, to the shaft Q. Now as the motor R is reversible, it is evident that the shaft Q can be driven in either direction for turning the drums P,

. to wind up or unwind the cables or ropes P.

In order to lock the drums P in position at the time the ropes or cables P are wound up and the cover C is in the raised position shown in Fig. 4, the following arrangement is made: On the worm P is secured or formed a brake wheel T engaged by a brake band made in sections T and T pivotally connected with a lever T (see Figs. 1 and 2), connected by an adjustable link T with a bell crank lever T fulcrumed on the overhead frame-work A, and pivotally connected by a link T with the lever P, so

that when the latter is swung to the left in the inverse direction of the arrow a, then the sectional brake band T, T is closed around the brake wheel T, to hold the worm P against accidental turning. The lever P is adapted to be locked in place in either its normal or brake applied positions, by engaging a notched bar P shown in Figs. 1 and 2.

In order to raise and lower the false perforated bottom B in the vat A, and, when dyeing loose material, to swing the said bottom B into an inclined or a discharging position, as shown in Fig. 4:, the following arrangement is made: The bottom B is provided on its upper surface with short chains B B adapted to be engaged at their outer links by hooks B, B held on ropes B, B extending through the joint between the flange C and the offset A to the outside of the vat, as indicated in Fig. 3. Now after the cover C has been moved into the raised position shown in Fig. 4:, the operator takeshold of the ropes B and B and pulls the normally folded chains B B up outward to the top of the vat, to then disconnect the hooks B*, B from the chains B B and to engage the latter with the hooks U and V on the ends of ropes or cables U and V, extending upwardly and winding and unwinding on drums U and V secured on transverse shafts U ,V",journaled in suitable bearings on the overhead framework A. On the shafts U and V are secured worm wheels U V in mesh with worms U V, mounted to turn loosely on the driven shaft Q, and provided wit-h clutch members U, V, adapted to be engaged by clutch members WV and W, mounted to slide on and to turn with the driven shaft The clutch members and W" are engaged by shifting levers V connected by links W W with levers V fulcrumed on the overhead framework A, and arranged in the front and rear of the lever P previously described. N ow when the machine is running, and the shaft Q, is rotated, and the cover C has been swung into a raised position, as before explained, and it is desired to lift the false bottom B with the dyed material thereon out of the vat, then the ropes U and V are connected with the chains B B as previously explained, and then both levers V W are shifted simultaneously in the direction of the arrow a, to move the clutch members W and V into engagement with the clutch members U V to rotate the worms U and V simultaneously and consequently to rotate the worms U*, V the shafts U V and the drums U V in unison, to wind up the ropes or cables U and V. iVhen this takes place the perforated false bottom B with the material thereon is gradually lifted out of the vat A, and when the perforated bottom B is clear of the top of the vat A, then the operator moves the lever W to normal vertical position, thereby moving the clutch member W out of engagement with the clutch member V to stop the rotation of the worm V and winding up of the rope or cable V. The other rope or cable U keeps on winding up on the drum U so that the right-hand end of the perforated bottom B is raised while the left-hand lugs B of the bottom B rest against the left-hand end of the vat A, to serve as a fulcrum for the perforated bot-tom B, to swing into the inclined discharging position shown in Fig. 4. .Vhen this position is reached the operator returns the lever to the normal vertical position, so that the clutch member W moves out of engagement with the clutch member U,'to stop the rotation of the worm U for the time being. Retaining chains B are attached to the under side of the false perforate bottom B at the right-hand side thereof, and the said chains are attached to the bottom A of the vat at the left-hand side thereof, the chains lying normally slack in the circulating space A When the false bottom B is raised into discharging position, as above described and shown in Fig. 4L, then the chains B are drawn taut and hold the perforate bottom against moving to the right during the time the dyed material slides o-ff the perforate false bottom B. After the material is discharged from the perforated false bottom B, the latter may be returned to the vat, and for this purpose the attendant reverses the motor B, so as to rotate the shaft Q in the opposite direction. The operator next swings the lever WV to the left, to again drive the drum U but in a reverse direction, so that the rope or cable U unwinds to allow the perforated bottom B to swing downward into a horizontal position, and when this is reached the operator swings the lever V to the left, to engage the clutch member W with the clutch member W to rotate the drum V in a reverse direction, that is, in the same direction in which the drum U is running, so that both ropes or cables U and V unwind together and thereby lower the perforated bottom B in the vat A-until the lugs B of the bottom B rest on the bottom A. Then this has been done, the hooks U, V are disconnected fro-m the chains B B and then the hooks B B are re-connected with the chains and their ropes B, B extending to the outside of the vat, after which the fresh material to be dyed is placed on the bottom B and then the frame 0 with the cover C is swung downward, to engage the cover C with the top of the material and to seat the cover on the offset A as previously explained.

The inactive ropes or cables U and V are swung to one side, as indicated in Fig. 1, during the dyeing operation.

The worms U and V are adapted to be locked against accidental rotation at the time the perforated bottom B is held in the raised position shown in Fig. 4:, and for this purpose brake mechanisms are provided similar to the brake mechanism above described relative to the worm P so that further description of the same is not deemed necessary, it being understood, however, that each brake mechanism consists-of a brake wheel T, band T, T lever T link T", lever T and link T connected with the corresponding levers 7 and IV, as shown in Figs. 1 and 2.

The frame 0 and cover C when in a raised position are preferably locked by the use of a manually-controlled catch X, fulcrumed on the overhead frame-work A, to prevent the frame 0 and the cover C from accidentally swinging downward during the time the workmen are engaged in loading the vat A with new material to be dyed. The catch X is controlled bya downwardly extending cord X within convenient reach of the operator.

As shown in Figs. 6 and 7, the double valve I is provided with a valve body I and with two slide or gate valves I 1*, held on a common valve stem 1*, connected at its outer end with an operating lever I under the control of the operator. Now when the slide valves I I are in the position shown in Figs. 6 and-7, the pipe D is closed to the nozzles D and communication is established between the circulating pump E and the tank pipe Ifby way of the valve body P, so that the pump E can pump the dye liquor to the storage tank. hen the slide valves I I" are raised, the slide valve I closes the entrance to the tank pipe I, while the slide I moves into open position and establishes connection between the circulating pump E and the outflow pipe D, so that the pump E pumps the dye liquor into the vat A by way of the outflow pipe D and nozzles D.

The double valve H, shown in detail in Fig. 8, is similar to the double valve I and is provided with a valve casing H, in which are mounted the slide or gate valves H H held on a stem H, connected with an operating lever H WVhen the slide valves H H are in the position shown in Fig. 8, the valve H opens the pipe G and the valve H closes the return pipe D to the overflow chamber F, and communication is established between the pipe G and the end of the pipe D leading to the circulating pump E, so that when the latter is running the dye liquor in the vat A is pumped out by way of the well G, the pipe G valve H, circulating pump E, valve I and pipe I to the storage tank or other place.

The operation is as follows: When dyeing loose material, say a bale of cotton, it is placed in the empty vat A at the time the false perforated bottom B rests on the bottom A of the vat A, and the cover C and its supporting frame 0 are in an uppermost or raised position. After the material is in place on the false perforated bottom B, the frame 0 is swung downward into a horizontal position, and then the operator turns the screw rod N to move the cover G down into firm contact with the top of the material, to confine the same in the vat between the false perforated bottom B and the said cover C, the latter being also seated on the offset A*, as previously explained. l/Vater is now run into the vat A from any suitable source until the water flows through the cover F into the overflow chamber F, and fills the same so that the level of the water is about flush with the lower end of the cover F. Steam is now admitted through the pipe L, to heat the water approximately to the boiling point. The clutch shifting lever S is now moved to the left to engage the clutch member S with the clutch member E, and then the reversible motor R is started, to rotate the shaft E and to actuate the circulating pump E, for the latter to draw the water out of the overflow chamber F and force the water by way of the pipe D and nozzles D into the circulating space or chamber A for the water to move in a circular path around the well G, and force the dirt, or other extraneous matter, from the material into the well G. The water also rises through the perforations in the false bottom B and through the material and the perforations in the cover C, to finally flow by way of the perforated cover F into the overflow chamber F, to be returned to the circulating space A by the circulating pump E. The dissolved dye stuff is added to the water in the tank to form a dye liquor, which is now circulated through the vat A and the material, the same as the water and as above described. This operation is continued until the dye liquor has dyed the material and is sufliciently exhausted to warrant its removal, which is done as follows: The valves H and I are shifted to the positions shown in Figs. 7 and 8, so that the circulating pump draws the dye liquor out of the vat A by way of the well G, pipe G valve H, pipe D circulating pump E, valve I and pipe I, to a storage tank or other place of discharge, that is, if the dye liquor is still valuable it is stored for further use, but if its dyeing properties have been spent it may be allowed to run to waste from the pipe I.

If it is desired to follow the dyeing operation with clear water for washing the material the valve D is closed, the valve J is opened and the valve I is shifted to move the slide valve I into open position, andthe valve K is opened, so that the pump E now draws clear water in through the pipe J, valve J, pipe D and forces the water out by way of the pipe D and the nozzles D into the circulating space A from which the water rises through the perforations of the false bottom B through the material, the perforations of the cover C, to flow into the overflow chamber F and drain out of the same by way of the pipe K, to a suitable place of discharge. After the washing operation is completed, the water in the vat is drawn out of the same. The circulating pump E is now stopped by the operator shifting the lever S to the intermediate position shown in Fig. 1. The operator now turns the screw rod N so as to unseat the cover C, and then the frame 0 is unlocked by removing the pin 0 and swinging the link 0 into open position, as shown in Fig. 4;. The operator now shifts the lever S to the right, so as to connect the clutch member S with the clutch member Q}, and then the motor R is started, to rotate the shaft Q. The operator now swings the lever P to the right, to engage the clutch member P with the clutch member P to cause turning of the drum P, as previously described, with a View to wind up the rope or cable P and thereby swing the frame 0 and with it the cover C upward into an open position. The latch X is now engaged with the frame 0, to lock the same in place against accidental downward swinging movement. The lever P is now swung in the reverse direction of the arrow a, so that the brake for the worm P is applied, as before stated, to hold the drum P against accidental return movement. The operator now pulls the chains B B upward,oby the use of the ropes B B and then connects the chains B B with the hooks U, V, after which the levers VV V are moved to the right, to throw the clutch members W and W into engagement with the clutch members U, V, to rotate the drums U and V in unison, to wind up the ropes or. cables U and V, with a View to lift the false perforated bottom B to the top of the vat A with the material resting on the said bottom. The rotation of the drum V is now stopped by the operator shifting the lever V back to normal position, to throw the clutch member W out of engagement with the clutch member V The rotation of the drum U is continued, so that the perforated false bottom B is now swung into the inclined discharging position, shown in Fig. 4, for the dyed material to slide off the said bottom to one side of the machine, into a suit able supporting receptacle or other device.

It is understood that after the perforated false bottom B reaches the discharging p0- sition, the lever W is moved to the left, to move the clutch member WV out of engagement with the clutch member U and to apply the brake for the worm U When it is desired to return the perforated false bottom B into the vat A, then the motor R is reversed, to rotate the shaft Q in the opposite direction, and then the lever W is moved to the right to engage the clutch member W with the clutch member U to rotate the drum U in the opposite direc tion, for the rope or cable U to unwind and to allow the false perforated bottom to swing into horizontal position, and when this takes place the other drum WV is started to unwind the rope or cable WV, to allow the false perforated bottom B to descend in the vat A, until its lugs B rest on the bottom A, and the above described opera tion is repeated.

When dyeing yarns on a beam M, the solid cover C is secured to the underside of the perforate cover C by .the screws C and the plug h 5 is unlocked and removed, and then the beam M with the yarn thereon is placed on the false bottom B, raised to the top of the vat A for the purpose, and while the covers C, C are held in raised position. The bottom B with the beam M thereon is now lowered into the vat A and when the false bottom B rests on the vat bottom A, then the beam M is shifted to the right to engage the open end of the hub M with the seat F"; and then the wedge M is insertedto draw the'hub M in firm contact with the packing F The covers C, (1* are now swung down and locked in place. The circulating pump E is now started to circulate the dye liquor through the yarn on the beam M, as previously explained, the dye liquor passing from the vat A by way of the perforate hub M into the overflow chamber F, to be returned to the circulating pump. A washing of the yarn on the beam M may follow by proceeding in the manner above described relative to washing the dyed loose material. After the dyeing operation of the yarn is completed, the covers C, C are swung up into open position, the wedge M is withdrawn and the beam M is shifted to the left until the shaft M clears the seat F and then the false bottom B with the beam M thereon is raised to the top of the vat, to permit of conveniently removing the beam M from the false bottom B. Another beam with yarn thereon can now be placed in posit-ion on the false bottom B, and the above described operatic-n is then repeated.
